ion, was responsible for introducing many
of the technical terms connected with electrolysis, like electrolyte
for the liquid through which the electric current is passed, and anode
and cathode for the positive and negative electrodes respectively. He
also established the laws of the process itself. But most people
remember his name in connection with his practical demonstration of
electromagnetic induction.

In France Andre-Marie Ampere (1775-1836) carried out a complete
mathematical study of the laws which govern the interaction between
wires carrying electric currents.

In Germany in 1826 a Bavarian schoolmaster Georg Ohm (1789-1854)
had defined the relationship between electric pressure (voltage),
current (flow rate) and resistance in a circuit (Ohm's law) but 16
years had to elapse before he received recognition for his work.

Scientists were now convinced that since the flow of an electric
current in a wire or a coil of wire caused it to acquire magnetic
properties, the opposite migh
